the mouth wash thing doesn't appeal to me at all. As for ordering ahead, the cost is about $40 for a mid range brand like Absolute, J Walker or J Beam. Drinks on NCL will run about $4.50 for beer I think (I am not a beer drinker) The drink of the day will run about $5:00 to $6:00 and regular cocktails in the $6.00 range plus 15% gratuity on all the above. It is wine that is really a bummer: figure anywhere from $6.00 to $8.00 per glass. The best line for not so pricey drinks in Princess, but I am sure they will join the rest very soon. NCL prices run similar to HAL and Celebrity. NMnita
